Playback works with no issues, except for the tray which opens and then closes right away. Playback is spot on and sounds great. I let a couple discs play though.

Unit is in awesome shape for its age very little scratches or worn spots on the unit. Has light rust on rear corner, you don't see it unless you look, see pictures. Thanks for looking
